Purpose. To assess correlations between volumetric first-order texture parameters on baseline MRI and pathological response after neoadjuvant chemotherapy (NAC) for locally advanced breast cancer (BC). Materials and Methods. 69 patients with locally advanced BC candidate to neoadjuvant chemotherapy underwent MRI within 4 weeks from the start of therapeutic regimen. T2, DWI, and DCE sequences were analyzed and maps were generated for Apparent Diffusion Coefficient (ADC), T2 signal intensity, and the following dynamic parameters: k-trans, peak enhancement, area under curve (AUC), time to maximal enhancement (TME), wash-in rate, and washout rate. Volumetric analysis of these parameters was performed, yielding a histogram analysis including first-order texture kinetics (percentiles, maximum value, minimum value, range, standard deviation, mean, median, mode, skewness, and kurtosis). Finally, correlations between these values and response to NAC (evaluated on the surgical specimen according to RECIST 1.1 criteria) were assessed. Results. Out of 69 tumors, 33 (47.8%) achieved complete pathological response, 26 (37.7%) partial response, and 10 (14.5%) no response. Higher levels of AUCmax (p value = 0.0338), AUCrange (p value = 0.0311), and TME75 (p value = 0.0452) and lower levels of washout10 (p value = 0.0417), washout20 (p value = 0.0138), washout25 (p value = 0.0114), and washout30 (p value = 0.05) were predictive of noncomplete response. Conclusion. Histogram-derived texture analysis of MRI images allows finding quantitative parameters predictive of nonresponse to NAC in women affected by locally advanced BC.

Primary Chemotherapy

10779 Background: Primary chemotherapy is becoming the standard of care for locally advanced breast cancer. Recently tested regimens using new drugs have been showing better results than usual anthracycline based treatments. Methods: From April 1998 through April 2004, 104 patients (18 stage IIA; 36 stage IIB; 13 stage IIIA; 33 stage IIIB; 4 stage IV) were included in the trial and received three cycles of docetaxel 75 mg/m2 and epirubicin 50 mg/m2 (q3w). Patients with stable or progressive disease were excluded from the trial, receiving alternative treatment. Those with partial response after three cycles but still not suitable for conservative surgery received up to 3 additional cycles. Following completion of the chemotherapy regimen, tumour response was assessed and appropriate surgery performed. Pathological response was evaluated in excised specimens. Results: According to the UICC criteria for clinical evaluation, 79 pts (76%) had objective regression (14 CR and 65 PR); 21 resulted in stabilised disease and 4 showed progression (24%). There was no toxicity in 62 patients, grade I/II in 4 and grade III/IV in seven patient. Ninity-nine patients became eligible for surgery (95%); 60 underwent conservative surgical treatment (60.6%) and in 39 patients a modified radical surgery was done (39.4%). No axyllary involvement were detected in 22 patients, other 23 had 1–3 positive nodes and 54 had 3 or more positives node in axillary dissection. 338 chemotherapy cycles were given, with an average of previously expected 3.25 cycles per patient. Conclusions: Our study demonstrates a high response rate with primary docetaxel and epirubicin chemotherapy in locally advanced breast cancer and high axillary envolvement group, enabling conservative surgery to take place and carrying no significant toxicity. Survival rate was directly linked to pathological response and complete response was associated to highest rate of survival in the group. No significant financial relationships to disclose.
